The triangular track drive system on Sakai’s CV550 single-drum vibratory roller can climb 45-degree slopes while compacting. The vibratory drum delivers more than 50,000 pounds of centrifugal-force output. The CV550 is powered by a 169-hp turbocharged Isuzu diesel. Two configurations are available: a smooth drum for semi-cohesive soils, and a padfoot drum for cohesive soils. A failsafe braking system, ROPS, and seat belts are standard equipment.
